摘要:
通过溶液法混炼工艺，以碳纳米管(CNTs）和石墨烯（GE）为添加剂制备出系列氢化丁腈橡胶（HNBR）/CNTs/GE复合材料，研究了微纳碳材料对HNBR硫化特性、力学性能及耐热氧老化性能等的影响。结果表明，微纳碳材料的加入延长了HNBR的正硫化时间、增大了转矩差。微纳碳材料对HNBR基体具有良好的改性效果，当GE与CNTs的混合质量比为1/2时，与HNBR基体相比，复合材料的拉伸强度提升了23.9%、耐撕裂性能提升至3.2倍；受微纳碳材料超共轭结构的影响，在180 ℃下老化24 h后复合材料的耐老化系数达到HNBR基体的5.2倍，老化后的交联密度与基体相比要小2个数量级。HNBR复合材料相比橡胶基体，其低温性能如玻璃化转变温度向高温区移动，最大热分解速率对应的温度也向高温区偏移。
Abstract:
A series of hydrogenated nitrile rubber (HNBR)/carbon nanotubes (CNTs)/graphene (GE) composites were prepared using a solution mixing process, with CNTs and GE as additives. The effects of micro-nano carbon materials on the vulcanization characteristics, mechanical properties, and thermal-oxidative aging resistance of HNBR were investigated. The results indicated that the incorporation of micro-nano carbon materials prolonged the optimal vulcanization time of HNBR and increased the torque difference. The micro-nano carbon materials exhibited excellent modification effects on the HNBR matrix. Compared to the pure HNBR matrix, the composite with a GE to CNTs mass ratio of 1/2 showed a 23.9% increase in tensile strength and a 3.2 times improvement in tear resistance. Owing to the hyperconjugated structure of the micro-nano carbon materials, the aging resistance coefficient of the composite reached 5.2 times that of pure HNBR matrix after 24 h of aging at 180 ℃. Furthermore, the crosslinking density of the aged composite was two orders of magnitude lower than that of the matrix. Compared to the rubber matrix, the glass transition temperature and maximum thermal decomposition rate of HNBR composites shifted toward higher temperatures.
